Abstract

PURPOSE:To perform optimum direction control of a combine by controlling the braking power of a lateral steering brake in such a manner as to keep the running distance difference of the right and left driving apparatuses at a constant level during the correction of the moving direction based on the detection of the culms with a direction sensor. CONSTITUTION:The right and left culm rows are detected by a direction sensor and the right and left steering brakes 3 are controlled by a direction controlling apparatus based on the detection result of the culm rows. In the case of outputting a correction signal of the direction based on the direction sensor, the braking power of the right and left steering brakes 3 are independently controlled by a brake-controlling apparatus 6 in such a manner as to keep the difference between running distances of the right and left driving apparatuses 5 at a constant level.

In this directional control, if the braking force of the left and right steering brakes is applied in the same way depending on the inclination of the vehicle body or the difference in the shared loads received by the left and right traveling gears, the traveling gear on the side of the vehicle body on the slope or on the side with the heavier shared load will move. Since the resistance is large, the vehicle is braked strongly, and the direction of movement of the vehicle body is shifted to one side, and the tip of the cutting rod of the cutting device may thrust into the adjacent culm row, making it difficult to control the direction properly.
